Price for a NEC-violation
In this talk I will discuss theories which violate the Null Energy Condition (NEC). In particular I will show that the NEC-violation is only possible for systems with the Hamiltonian unbounded from below, provided these systems are Lorentz symmetric. I will also discuss the relation of NEC- violation with superluminality and consequences of this relation for alternative theories of the early universe.
